The competition will determine a grand-prize winner for the ball, which in the past has encouraged participants to don caveman- and cavewoman-inspired attire, frequently revolving around animal print and accessories such as club or Pebbles-style bones in hair -- anything prehistoric, really. The contest is sponsored by Orlando philanthropist Harriett Lake, who will also serve as a judge.

The event includes dining, drinks, a silent auction and a "diamond dig" in the DinoDigs exhibit of the science center. There will be themed music and entertainment.
